Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of distributed technology, and in particular to a remote file processing method, device, equipment, medium and program product. BACKGROUND

[0002] Under the background of the vigorous development of modern computer information technology, the analysis and processing of various types of digital information all depend on files on the file system, and files usually need to be loaded into local memory before they can be normally used.

[0003] For a remote file with a large amount of data, the time waiting for the complete transmission of the file will be very long, and the transmission of the remote file is easily affected by the stability of the network, resulting in problems such as data damage or file transmission failure, affecting the subsequent use of the file, and when the remote file is transmitted through the network, the network message of the file transmission is easily eavesdropped by hackers, thereby causing security risks such as information leakage. SUMMARY

[0004] The present application provides a remote file processing method, device, equipment, medium and program product, which can realize remote downloading of super large files and improve the transmission stability of super large files.

[0005] According to an aspect of the present application, a remote file processing method is provided, which is executed by a user terminal, a server and a file database in a remote file processing system, comprising:

[0006] When the file database determines that the user terminal initiates a download request for a first file, it generates a plurality of binary stream cut blocks according to the first file and sends each binary stream cut block to the server;

[0007] The server groups the binary stream cut blocks according to the number of ports, establishes a corresponding relationship between each cut block group and each port, and transmits the binary stream cut blocks to the user terminal through the ports corresponding to each cut block group and the first network transmission protocol;

[0008] After the user terminal determines that the reception of the binary stream cut blocks is complete, it restores the first file according to each binary stream cut block and stores the first file.

[0009] Optionally, when the file database determines that the user terminal initiates a download request for a first file, it generates a plurality of binary stream cut blocks according to the first file, comprising:

[0010] When the file database determines that the user terminal initiates a download request for a first file, it performs binary encoding on the first file to obtain a binary file;

[0011] The file database is used to divide the binary file according to a predefined chunk size, and each binary stream chunk is labeled according to the order of the binary stream chunks in the binary file.

[0012] The advantage of this arrangement is that the binary file is divided according to a predefined chunk size, which is more flexible than directly transmitting the entire large file in an unstable network environment or limited bandwidth. During network transmission, the chunk method makes each chunk relatively independent and sequentially associated. Even if a chunk is lost or damaged during transmission, the problematic chunk can be retransmitted through the retransmission mechanism, ensuring that the final received file is complete and accurate, thereby enhancing the reliability of the entire file download process.

[0013] Optionally, the user terminal is used to restore the first file according to the binary stream chunks after determining that the reception of the binary stream chunks is complete, including:

[0014] The user terminal is used to combine the binary stream chunks according to the labels of the binary stream chunks after determining that the reception of the binary stream chunks is complete.

[0015] The user terminal is used to decode the combined binary stream total file to restore the first file.

[0016] The advantage of this arrangement is that during network transmission, the file is divided into multiple binary stream chunks for transmission. Due to the complexity of the network environment, these chunks may arrive at the user terminal in different orders, or individual chunks may be delayed during transmission. By combining the binary stream chunks according to their labels, it can be ensured that these chunks can be combined into a complete binary stream total file in the correct order.

[0017] Optionally, the binary stream chunks are transmitted to the user terminal through the ports corresponding to each chunk group and the first network transmission protocol, further including:

[0018] When the service terminal determines that the transmission of at least one binary stream chunk in the target chunk group fails, it controls the target chunk group to be retransmitted, and when it determines that the retransmission of the target chunk group fails, it switches the target chunk group from the current port to the target port for transmission.

[0019] When the service terminal determines that the transmission of each chunk group is interrupted, it records the breakpoints of each chunk group, and when it determines that the port transmission has returned to normal, it continues the transmission according to the breakpoints of each chunk group.

[0020] The advantage of the arrangement is that the server can better cope with various complex network scenarios, whether it is a short network fluctuation or a long network failure, and the system has corresponding measures to ensure smooth file transmission, thereby improving the adaptability of the entire file transmission system in different network environments.

[0021] Optionally, the remote file processing method further comprises:

[0022] Through the user end, when the user initiates a remote access operation on a second file, a target access request for the second file is sent to the server end;

[0023] Through the server end, when the target access request sent by the user end is received, it is determined whether the user end has target access authority, and when it is determined that the user end has target access authority, the access behavior of the user end copied by the second network transmission protocol is obtained;

[0024] Through the server end, the target byte stream is determined according to the access behavior, and the target byte stream is sent to the user end by using the second network transmission protocol, so that the user end performs a remote access operation on the second file according to the target byte stream.

[0025] The advantage of the arrangement is that fast remote access of large files can be realized before the user end downloads the file, solving the problem in the prior art that the entire file needs to be downloaded to the local before the file can be processed, and improving the user remote access experience.

[0026] Optionally, through the server end, the target byte stream is determined according to the access behavior, comprising:

[0027] Through the server end, the access behavior is played back, the byte stream used in the playback process is obtained, and the byte stream used in the playback process is determined as the target byte stream.

[0028] The advantage of the arrangement is that the target byte stream can be quickly extracted and fed back to the user end by playing back the access behavior to obtain the target byte stream, so that the file content related to the current access operation of the user end can be quickly displayed on the user end, thereby improving the access efficiency.

[0029] According to another aspect of the present application, a remote file processing device is provided, which is cooperatively executed by a user end, a server end and a file database in a remote file processing system, comprising:

[0030] A file chunking module is configured to, through the file database, when it is determined that the user end initiates a download request for a first file, generate a plurality of binary stream chunks according to the first file, and send each binary stream chunk to the server end;

[0031] The chunk transmission module is configured to group the binary stream chunks according to the number of ports, establish a corresponding relationship between each chunk group and each port, and transmit the binary stream chunks to the user terminal through the ports corresponding to each chunk group and the first network transmission protocol.

[0032] The file restoration module is configured to restore the first file according to each binary stream chunk and store the first file after determining that the receiving of the binary stream chunks is completed.

[0033] According to another aspect of the present application, an electronic device is provided, which comprises:

[0034] at least one processor; and

[0035] a memory connected to the at least one processor in communication; wherein

[0036] The memory stores a computer program executable by the at least one processor, and the computer program is executed by the at least one processor to enable the at least one processor to execute the remote file processing method according to any one of the embodiments of the present application.

[0038] According to another aspect of the present application, a computer program product is provided, which comprises a computer program for implementing the remote file processing method according to any one of the embodiments of the present application when executed by a processor.

[0039] The technical solution of the embodiments of the present application can realize the remote downloading of large files, effectively improve the stability and transmission efficiency of file transmission, and ensure the file security and correctness of the downloaded files by using a file database to generate a plurality of binary stream chunks according to a first file when a user terminal initiates a downloading request for the first file, sending each binary stream chunk to a server, grouping the binary stream chunks according to the number of ports using the server, establishing a corresponding relationship between each chunk group and each port, transmitting the binary stream chunks to the user terminal through the ports corresponding to each chunk group and the first network transmission protocol, and restoring the first file according to each binary stream chunk and storing the first file using the user terminal after determining that the receiving of the binary stream chunks is completed.

[0089] S310, by the user terminal, when the user initiates a remote access operation of a second file, sending a target access request for the second file to the server.

[0090] It can be understood that for the loading of a remote file, a common method is to perform network transmission of the file to a local disk in advance, and after the complete transmission of the file, the file is read from the disk to the memory for use, but if the data volume of the remote file is large, the waiting time for the complete transmission of the file will be very long, which seriously affects the user experience or the efficiency of data analysis and processing of the program, therefore, in the embodiment, a remote file processing method is proposed, which enables the user terminal to quickly and conveniently perform a remote file access operation before the file is downloaded.

[0099] Optionally, through the document security protection system, when it is determined that the user terminal does not have the target access permission of the second file, the file processing failure information is returned to the user terminal.

[0100] It can be understood that for a large file, the user only involves a small part of the file when viewing or editing, and the access behavior of the user terminal can refer to the part of the file currently viewed or edited by the user, for example, the access behavior of the user terminal can be to view the second page of the second file.

[0104] Through the server, the access behavior is replayed, the byte stream used in the replay process is obtained, and the byte stream used in the replay process is determined as the target byte stream.

[0105] Optionally, the second network transmission protocol can be Figure 2 The server bytes protocol in the above-mentioned, which is also a user's self-developed protocol, the second network transmission protocol can be used to transmit the byte stream required for current viewing or editing of the file, so as to achieve the purpose of fast access.

[0106] The technical scheme of the embodiment of the application, by using the user terminal, when the user initiates the remote access operation of the second file, the target access request for the second file is sent to the server, by using the server, when the target access request sent by the user terminal is received, it is determined whether the user terminal has the target access authority, and when it is determined that the user terminal has the target access authority, the access behavior of the user terminal copied by the second network transmission protocol is obtained, the target byte stream is determined according to the access behavior, and the target byte stream is sent to the user terminal by using the second network transmission protocol, so that the user terminal performs remote access operation of the second file according to the target byte stream. The mode can realize fast remote access of large files before the user terminal downloads the file, solve the disadvantages that the complete file needs to be downloaded to the local before the file can be processed in the prior art, and improve the user remote access experience.
